Smart color-changing glass is like a magical wizard, capable of automatically adjusting its color and transparency based on environmental changes such as light intensity, temperature, or electric field variations. This allows it to regulate indoor light and temperature, achieving goals like energy saving, emission reduction, and enhanced comfort. On scorching summer days, it can block intense sunlight, reducing the load on indoor air conditioning. In the cold of winter, it allows ample sunlight to stream in, adding warmth to the interior.

Physical Vapor Deposition (PVD) is an important technique for preparing tungsten disulfide thin film on material surfaces. Due to its unique physical and chemical properties, WS₂ thin film is widely applied in fields such as aerospace, mechanical manufacturing, and the automotive industry.

Metal-doped modification of tungsten disulfide (WS₂) is a method to enhance its properties by introducing other metal atoms into WS₂, holding significant importance in the field of materials science.

In the cutting-edge field of materials science, tungsten oxide thin films are gradually emerging as a focus of attention for many researchers due to their unique and outstanding properties. This seemingly ordinary thin film material actually harbors tremendous potential and has demonstrated remarkable application prospects in numerous fields.
